WET OXIDATION OF PHENOL BY HYDROGEN-PEROXIDE USING HETEROGENEOUS CATALYSIS FE-ZSM-5 - A PROMISING CATALYST

This letter presents an original approach to the treatment of phenolic aqueous wastes using H2O2 with heterogeneous catalysts. The experimen tal results indicate that the system using Fe-ZSM-5 zeolite with MFI s tructure is promising since it allows total elimination of phenol and significant total organic carbon (TOC) removal under mild working cond itions. Moreover, Fe-ZSM-5 remains active after successive runs. Compa red with processes using homogeneous catalysis, the possibility of ind uced pollution caused by the metal ions in the solution is avoided.
